VALVE Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 4:. 1907- Serial No. 360,527.

To all whom it may concern: I

Be it known that I, PHILIP W. MARETT, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inValves, of which the following is a specification.

My invention relates to valves and more particularly to a compound valvefor use in connection with faucets, shower apparatus and the like, andthe object in view is to provide a simple and cheap construction and onewhich will be as nearly frictionless as is possible in order to outliveother structures of this character.

My invention consists broadly in providing a suitable casing havingseparate hot and cold water inlet connections and a single universaloutlet, in combination with noveland substantially frictionless means,manually operable, for closing or opening either the hot or cold wateror both as desired.

My invention fiu'ther consists in the following features of constructionand arrangement hereinafter described and pointed out in theaccompanying drawings, in which,

Figure 1 is a front elevation of my valve, the casing being partlybroken away. Fig. 2 is a cross section therethrough. Fig. 3 is adiagrammatic view with the casing removed and showing the hot and coldwater inlets closed. Fig. 4 is a similar view showing the cold water on.Fig. 5 is a similar view showing both hot and cold water inlets open,and, Fig. 6 is a similar view showing the hot water on.

Referring to the figures, the casing 1 is provided with an enlargedsocket portion 2 forming a bearing for the reduced end 3 of theoperating spindle 4. The front plate 5, connected to the casing 1 by thescrew cap 6, is provided with a centrally located nipple portion 7through which said spindle is mounted and at the end of which I arrangea stufiing box 8. An operating handle 9 is mounted on the outer end ofthe spindle 4 by means of a washer 10 and a screw nut 11, and saidhandle is provided with a right angle arm 12 having an indicating memberor pointer 13 arranged at the end thereof.

Through the casing 1 are arranged the hot water inlet 14, the cold waterinlet 15 and the single universal outlet 16, each of which is providedwith a constricted mouth 17 for a purpose hereinafter described.

On the operating spindle 4 is mounted a pair of spiders 18 rigidly heldspaced apart by means of the transverse strips 19 and comprisingangularly extending legs 20, 21, and 22 carrying roller valves 23, 24and 25 respectively. The roller valves 24 and 25, are rotatively mountedon short shafts rigidly held between the corresponding legs of thespiders 18 and are adapt ed to regulate the cold water inlet on themovement of 23 is, on the contrary, provided with a transverse slot 26,in which the rotating spindle 27 of said roller 23 is mounted to slide;the said roller being mounted through the arms 28 of an independentbracket having its sleeve 29 loosely mounted about the spindle 4. Itwill thus be seen that I am able to accomplish my object by the use ofonly three rollers forming valves adapted to be seated against theconstricted mouth 17 of both hot and'cold inlets, one of said valveshaving a delayed movement in order that the opposite inlet may be openedwithout' moving the same from its seat as I will now describe.

Referring to Figs. 3 to 6, in which the different positions are shownwith the effect indicated on the face of the front plate; andspecifically to Fig. 3, the hot and cold inlets are shown closed by theroller valves 23 and 25, the valve 24 not being in use.

Referringto Fig. 4 it will be seen that when cold water is desired andhandle 9 moved correspondingly, the roller valve 25 will be moved off ofits seat and open the cold water inlet 15, but the movement of theroller valve 23 will be delayed and will remain seated, as shown, byreason of its slidable mounting in slot 26. As shown in this figure theroller is at the extremity of the slot when the cold water is on andwhen a mixture of cold. and hot water is desired and handle 9 movedaccordingly the valve 23 will be moved from its seat thus opening thehot water inlet, as shown in Fig. 5. Up to this time the valve 24 hasremained in non-use but when hot water only is wanted the movement ofthe handle 9 is continued with the result that said valve 24 is seatedon the mouth of the cold water inlet 15.

Having fully described my invention, what I claim 1. In a valve, thecombination of a valve seat and a roller mounted to be seated thereon,and having a delayed movement with relation to its mounting,substantially as described.

2. In a valve, the combination of a valve seat and an independentlyrevoluble roller adapted to be seated thereon, said roller beingmountedto rotate about a central axis, and having; a delayed movement withrelation to its mounting, substantially as described.

3. In a valve of the class described, the combination with a casinghaving hot and cold water inlets and a universal outlet, of suitablymounted rollers adapted to be operntcd to open and close said inlets andsaid outlet, one of said rollers having a delayed movement with relationto the others, substantially as described.

-l. In a valve of the class described, the combination with a casinghaving hot and cold Water inlets and a uni versal outlet, of suitablymounted independently revoluble rollers arranged in spaced relationWithin said casing, and bearing against the wall thereof, said rollersbeing adapted to be operated to open and close said inlets and saidoutlet, one of said rollers havinga delayed movement with relation tothe others, substantially as described.

5. In a valve of the class described, the combination with a casinghaving hot and cold water inlets and a universal outlet, of a pluralityof independently revoluble the handle 9 t0 (310% 01 open t e S e, asShown most rollers mounted to rotate about a central axis and arclearlyin Figs. 3 to 6. The leg 20 carrying roller valve l ranged to open andclose said inlets during their rotative movement, one of said rollershaving a delayed movement with relation to the others, substantially asdescribed.

6. In a valve of the class described, the combination with a casinghaving hot and cold water inlets and a universal outlet, of a rotatingframe mounted therein, a pair of independently revoluble rollers mountedin spaced relation in, and rotating with, said frame, a supplementalframe loosely mounted within said main frame and a roller revolublymounted in said supplemental frame and having a limited sliding movementon the rotation of said main frame, substantially as described. Intestimony whereof I affix my signature in presence of two witnesses.
